I've had a positive response from the company and am now seeking somebody to volunteer a pre-war EMI CRT for rebuilding. Other early Pyrex CRTs might also be relevant - I don't know what types were then used in the USA.

Cost would be $1000 + shipping both ways. Work would be done as a best effort. Obviously success cannot be gauranteed.

Greetings,
I see this post is old but I'm a new member so it's new to me. Was any progress made with sending a tube to EMI for rebuild ? Seems like the subject just got dropped. Maybe it's in another post? Any Info?

Jeffrey,
Thanks for sending me to your article. It was very interesting. I love reading about all the dedicated people trying to save our hobby as well as save the history of television. It's a shame so much has already slipped away. At least it seems to me that the more people interested, the more hope their is of preserving the history. It's a frustrating fact that as each day goes by someone cleans out a basement or garage and not knowing the value, throws out and or destroys another piece of history. Everyday we lose a bit more. I'm glad at least a few of us are trying to save a small piece of the past.
